My Wi-Fi is turned off at random and remains inactive until restart. This seems to happen after about 5 or 10 minutes. I tried all the dozens of solutions released in this forum, but it did not work. When I boot in Windows mode, WiFi works fine. Funny thing is, I have Linux versions that are one and two decades old, and they work well. I've turned off WiFi sleep, as well as a bunch of other things.
I get many of these mistakes when this happens. It looks like there's a problem with the way DMA is tried:

Any help is greatly appreciated. I literally tried dozens of solutions in this forum and none helped.
I would really like to work with a modern Linux version as the included compilers and other things could be much improved.

Yesterday, when an external USB drive was formatted, I thought that I initially made a mistake when I chose the wrong drive. Everything was so good, nothing went wrong at first.

After all that happened, my computer worked fine. I went to bed, woke up today and started working, and everything was fine (I did not turn off last night when I was in sleep mode). However, I tried to install this dev tool and make sure everything worked. I restarted it and it does not start properly, just an "unknown file system" error when I boot.

I used a live USB Ubuntu (Try Ubuntu) to restore and followed some instructions on using the boot repair from: https://www.howtogeek.com/114884/how-to-repair-grub2-when-ubuntu- wont-boot /

I did that, trying to reboot, and still ended up with the same file system error. Remember, I've already checked all file systems with Grub's commands to see if they were loaded from the right partition, but they all came up and had no ideas.

I added the video drivers to PPA and installed the 415 driver, but it appeared that my 940MX was no longer used. So I tried to get back to the 390. However, I made the mistake of removing the PPA before I left. When I tried to switch back to the 390 driver, Ubuntu spat a bug – I can not remember the message exactly, though I think something was not found in the cache.

After I restarted my system, the boot process stalled on a screen displaying countless messages about starting the NVIDIA persistence daemon and stopping the NVIDIA persistence daemon. To boot the system, I had to invoke and use the recovery mode Prime-select information, If I use the Nouveau driver, the system can boot, but my laptop does not seem to use my GPU.

To run nvidia-smi produces the following:

NVIDIA SMI failed because it can not communicate with the NVIDIA driver. Make sure the latest NVIDIA driver is installed and running.

I followed the advice here, but unfortunately it did not help. I tried to remove any residue that the 415 driver may have left behind. At first I looked at this thread, but with regard to the page linked by it, the directory /usr/local/cuda-X.Y does not exist (as in, there is no cuda-related directory) and the link / usr / bin / nvidia-uninstall points to NVIDIA Installerbut that does not exist. So I removed the packages as recommended according to this answer. I then set the driver in the software settings to NVIDIA 390, so everything was reinstalled. However, I can not boot by restarting with the selected NVIDIA GPU.

The result of dpkg -l | grep nvidia At the time of writing is the following:

I'm new to Ubuntu, and after installing Ubuntu on my PC, I experience an extremely slow WiFi connection (but faster under Windows). I tried to disable the 802.11n and the Intel driver card, but I get the following error message (running sudo modprobe -r iwlwifi):

I tried to install Ubuntu 18.04.1 64-bit on a seemingly healthy machine Seagate Pipeline HD (Model ST3320310CS) SATA HDD. Each time a dialog box appears, there is a "apt configuration problem"Msgstr "Attempt to configure apt to install additional packages from the CDfailedThen I'm told that the installation failed. "In this Ubuntu installation, I used a USB key that was burned via Unetbootin, and this USB key allows me to see a lot of Ubuntu files being copied to my computer were. " HDD, but the installation can not be completed, I also tried another USB live key, but the result was identical: on both USB keys, the reviews of sha256sum were successful.

I've previously tried installing Ubuntu Mate 18.04.1 on the same hard drive on two different 64-bit computers (both with a USB stick and a DVD), and the message I received was very much the one above similar.

I ran the DST short test of the hard disk from the BIOS and it is passed. According to the screenshot for this hard disk (recorded via the Ubuntu Live USB stick) [NB AskUbuntu has refused to accept this png image in my post] is the rating for the disk "OK".

I am totally amazed why the installation is not completed. I have installed Ubuntu, Lubuntu etc. in the past without problems on used hard drives. However, I recently purchased this problematic hard drive from a local reseller, and although it was not shipped with any packaging, it looks unused. So I'm wondering if I have to somehow format it before installing? If so, I wonder how to proceed now with all the Ubuntu files already copied to.

Although I have gradually learned to do some very rudimentary technical things in Ubuntu (like the sha256sum check and some commands on the terminal), my know-how is still very limited. Given this and the fact that only Ubuntu is installed on this hard disk (and NOT on Windows), I wonder if you suggest following the instructions on this help page to install a new hard drive here:

https://help.ubuntu.com/community/InstallingANewHardDrive

The above instructions are extremely daunting for me at the moment! Do you think I might find it easier to see Seagate? "Disc Wizard" Software (available online according to sticker on the hard disk)?

I have the Ryzen 3 2200G with integrated graphics. When I connect the HDMI to the motherboard and change the settings for the integrated graphics in the BIOS, it boots correctly, but when I connect HDMI to the graphics card (ZOTAC GeForce GTX 1060), it asks for a cryptographic password flashes for a while and stops on the following screen

Freeze the screen

How do I solve it? I do not think there should be a problem with my partitions because they could not be booted in the Integrated Graphics use case, and I tried setting the use_lvmetad switch from 1 to 0, but this is still displayed.

I have also installed the NVIDIA drivers. Thank you in advance. My kernel version is 4.15.0-43 and the installed NVIDIA drivers are in version 410
